Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Ankerwicklung eines Elektromotors aus einem Drahtmaterial mit im wesentlichen rechtwinklig miteinander verbundenen Wicklungselementen aus Metall, wobei jeweils gegenüberliegende Wicklungselemente endseitig durch jeweils gegenüberliegende Wicklungselemente in Form von Rechteck-Flachteilen miteinander verbunden sind.The invention relates to a method for producing a Armature winding of an electric motor made of a wire material connected to each other at substantially right angles Winding elements of metal, each opposite Winding elements end by each opposite Winding elements in the form of rectangular flat parts connected to each other.

Derartige Ankerwicklungen sind bekannt und kommen beispielsweise bei Asynchronmotoren zum Einsatz. Sie werden aus abgelängten Drahtstücken und ausgestanzten Blechteilen hergestellt, wobei die Drahtstücke und die Blechteile jeweils alternierend senkrecht angeordnet und endseitig miteinander verschweißt werden, so daß jeweils gegenüberliegende Wicklungselemente der Ankerwicklung von den Drahtstücken gebildet sind, die jeweils durch die einander gegenüberliegenden Blechteile endseitig miteinander verbunden sind. Die fertige Ankerwicklung ist folglich von wendelförmigem Aufbau und weist in Umfangsrichtung alternierend angeordnete Wicklungselemente auf, die einerseits von den gestanzten Blechteilen, andererseits von den abgelängten Drahtstücken gebildet sind.Such armature windings are known and come for example used for asynchronous motors. you will be made of cut wire pieces and stamped sheet metal parts manufactured, with the wire pieces and the sheet metal parts respectively alternately arranged vertically and end to each other be welded, so that each opposite Winding elements of the armature winding of the pieces of wire are formed, each through the opposite Sheet metal parts connected end to end are. The finished armature winding is therefore of helical Structure and has circumferentially alternately arranged Winding on, on the one hand of the punched Sheet metal parts, on the other hand of the cut to length Wire pieces are formed.

Nachteilig ist zum einen die beim Ausstanzen der Blechteile anfallende erhebliche Menge an Ausschußmaterial, zum anderen ist die Herstellung der Ankerwicklung aufgrund der vielen Schweißvorgänge insbesondere in handhabungstechnischer Hinsicht aufwendig und teuer.The disadvantage is on the one hand when punching the sheet metal parts accumulating considerable amount of waste material, on the other is the manufacture of the armature winding due to the many Welding processes, especially in handling technology Respectful and expensive.

Die US 1 796 422 A beschreibt eine Ankerwicklung, welche gänzlich aus Rechteck-Flachteilen gebildet ist. Dabei sind mehrere, jeweils ein Winkelstück bildende Wicklungselemente einstückig ausgebildet und endseitig miteinander verbunden, insbesondere verschweißt. Zwar läßt sich auf diese Weise die Anzahl an Schweißvorgängen vermindern, doch ist die Herstellung der durch mehrfaches Umbiegen einer stabartigen Lamelle erhaltenen, im wesentlichen L-förmigen Winkelstücke der Ankerwicklung aufwendig und zeitintensiv. Überdies fällt beim Ausstanzen der Lamellen noch mehr Ausschußmaterial an, da die gesamte Ankerwicklung aus den flachen Lamellen gebildet ist.US 1 796 422 A describes an armature winding which is formed entirely of rectangular flat parts. There are a plurality, each forming an elbow winding elements integrally formed and interconnected end, in particular welded. Although can be in this way reduce the number of welding operations, but is the Production of by repeatedly bending a rod-like Slat obtained, substantially L-shaped elbows the armature winding consuming and time consuming. moreover falls when punching the slats even more waste material because the entire armature winding is out of the flat fins is formed.

Der Erfindung liegt die Aufgabe zugrunde, ein einfaches und kostengünstiges Verfahren zur Herstellung einer Ankerwicklung eines Elektromotors aus einem Drahtmaterial vorzuschlagen, welches ein Anfallen von Ausschußmaterial weitestgehend verhindert.The invention is based on the object, a simple and cost-effective method for producing an armature winding to propose an electric motor made of a wire material, which an accumulation of committee material as far as possible prevented.

Erfindungsgemäß wird diese Aufgabe mit einem Verfahren der eingangs genannten Art gelöst, welches durch folgende Schritte gekennzeichnet ist :

  • Ablängen des Drahtmaterials zu Drahtstücken;
  • Biegen der Drahtstücke unter Bildung von wenigstens zwei Schenkel aufweisenden Winkelstücken;
  • Quetschen wenigstens eines Schenkels der Winkelstücke bis zumindest zur Fließgrenze des Drahtmaterials;
  • Beschneiden des gequetschten Schenkels der Winkelstücke unter Bildung eines endseitig mit dem anderen Schenkel desselben verbundenen Rechteck-Flachteils;
  • endseitiges Verbinden jeweils des anderen endständigen Schenkel wenigstens eines Winkelstücks mit dem endständigen Rechteck-Flachteil wenigstens eines weiteren Winkelstücks oder mit einem separaten Wicklungselement, insbesondere einem Rechteck-Flachteil, unter Bildung der Ankerwicklung.
According to the invention this object is achieved by a method of the type mentioned, which is characterized by the following steps:
  • Cutting the wire material into pieces of wire;
  • Bending the wire pieces to form at least two leg having elbows;
  • Squeezing at least one leg of the angle pieces up to at least the yield point of the wire material;
  • Trimming the crimped leg of the elbows to form a rectangular flat part connected end to end with the other leg thereof;
  • end-side connecting in each case of the other end leg of at least one angle piece with the terminal rectangular flat part of at least one further angle piece or with a separate winding element, in particular a rectangular flat part, to form the armature winding.

Die Erfindung zeichnet sich durch eine völlige Abkehr von den herkömmlichen Verfahren zur Herstellung einer gattungsgemäßen Ankerwicklung aus, indem sämtliche Wicitlungselemente der Ankerwicklung aus dem Drahtmaterial hergestellt werden. Hierbei werden die Drahtstücke zunächst unter Bildung von zwei oder mehrere Schenkel aufweisenden Winkelstücken bis zumindest zur Fließgrenze des Drahtmaterials gequetscht und der gequetschte Schenkel der Winkelstücke unter Bildung eines endseitig mit dem anderen Schenkel der Winkelstücke verbundenen Rechteck-Flachteils beschnitten. Der andere endständige Schenkel jeweils eines Winkelstücks wird schließlich mit dem derart erzeugten endständigen Rechteck-Flachteil jeweils eines weiteren Winkelstücks oder einem z.B. aus demselben Drahtmaterial gefertigten Rechteck-Flachteil unter Bildung der Ankerwicklung verbunden.The invention is characterized by a complete departure from the conventional method for producing a generic Armature winding off by all Wicitlungselemente the armature winding made of the wire material become. Here, the pieces of wire are initially under education of two or more legs having elbows to at least the yield point of the wire material bruised and the bruised leg of the elbows forming one end with the other leg of the Circled connected rectangle flat part. The other terminal leg each one of an elbow finally becomes with the so produced terminal Rectangular flat part of each another angle piece or a e.g. made of the same wire material rectangular flat part connected to form the armature winding.

Die Erfindung macht somit ein Ausstanzen der als Flachteile ausgebildeten Wicklungselemente der Ankerwicklung entbehrlich, was in einer erheblichen Verringerung an Ausschußmaterial resultiert. So entspricht die beim Beschneiden der gequetschten Schenkel der Winkelstücke anfallende Menge an Ausschußmaterial nur etwa 30% des beim Ausstanzen entsprechender Blechteile anfallenden Ausschusses. Ferner sind zur Herstellung der Ankerwicklung aufgrund der einstückigen Ausbildung wenigstens zweier benachbarter Wicklungselemente gegenüber dem Stand der Technik weniger Schweißvorgänge erforderlich, was die Durchführung des erfindungsgemäßen Verfahrens vereinfacht und insbesondere die Herstellungskosten der Ankerwicklung reduziert.The invention thus makes a punching as flat parts trained winding elements of the armature winding dispensable, resulting in a significant reduction in scrap material results. So that corresponds to when pruning the squeezed leg of the angle pieces accumulating amount Committee material only about 30% of the corresponding during punching Sheet metal resulting from scrap. Furthermore, the Production of the armature winding due to the one-piece Forming at least two adjacent winding elements less welding operations required compared with the prior art, what the implementation of the method according to the invention simplifies and in particular the production costs the armature winding is reduced.

Eine bevorzugte Ausführung sieht vor, daß die Drahtstücke zu im wesentlichen L-förmigen Winkelstücken gebogen werden, der eine Schenkel der L-förmigen Winkelstücke gequetscht und zu dem Rechteck-Flachteil beschnitten wird und jeweils das Rechteck-Flachteil wenigstens eines L-förmigen Winkelstücks endseitig mit dem anderen Schenkel wenigstens eines weiteren L-förmigen Winkelstücks unter Bildung der Ankerwi cklung verbunden wird. Eine Umfangswicklung der solchermaßen hergestellten Ankerwicklung besteht dann aus zwei endseitig miteinander verbundenen L-förmigen Winkelstücken.A preferred embodiment provides that the wire pieces be bent to substantially L-shaped elbows, the one leg of the L-shaped angle pieces squeezed and to the rectangle flat part is trimmed and respectively the rectangular flat part of at least one L-shaped angle piece at least one end with the other leg another L-shaped angle piece forming the Ankerwi Connected. A circumferential winding of such made armature winding then consists of two end connected L-shaped elbows.

Gemäß einer anderen bevorzugten Ausführung ist vorgesehen, daß die Drahtstücke zu im wesentlichen rechteckförmigen Winkelstücken gebogen, jeweils zwei gegenüberliegende Schenkel der rechteckförmigen Winkelstücke gequetscht und zu jeweils einem Rechteck-Flachteil beschnitten werden und jeweils das endständige Rechteck-Flachteil wenigstens eines rechteckförmigen Winkelstücks endseitig mit dem anderen endständigen Schenkel wenigstens eines weiteren rechteckförmigen Winkels tücks unter Bildung der Ankerwicklung verbunden wird. In diesem Fall weist eine Umfangswicklung der solchermaßen hergestellten Ankerwicklung ein rechteckförmiges Winkelstück auf, welches endseitig mit einem weiteren oder mehreren derartiger Winkel stücke verbunden ist.According to another preferred embodiment, it is provided that the wire pieces to substantially rectangular Elbows bent, two opposite each Legs of rectangular elbows squeezed and be cut to a rectangular flat piece and in each case the terminal rectangular flat part of at least one rectangular elbow end to end with the other terminal leg of at least one further rectangular Winkels tücks connected to form the armature winding becomes. In this case, a circumferential winding of the thus produced armature winding a rectangular Elbow on which end with another or several such angle pieces is connected.

Eine dritte bevorzugte Ausführung sieht vor, daß die. Drahtstücke zu im wesentlichen U-förmigen Winkelstücken gebogen werden, der mittlere Schenkel der U-förmigen Winkelstücke gequetscht und zu dem Rechteck-Flachteil beschnitten wird und wenigstens ein separates Wicklungselement in Form eines Rechteck-Flachteils endseitig mit wenigstens einem anderen Schenkel des U-förmigen Winkelstücks unter Bildung der Ankerwicklung verbunden wird. Eine Umfangswicklung der auf diese Weise erzeugten Ankerwicklung besteht dann aus einer aus dem U- förmigen Winkelstück und dem separaten Rechteck-Flachteil gebildeten Einheit, welche endseitig mit einer weiteren oder mehreren solcher Einheiten verbunden ist.A third preferred embodiment provides that the. Bent wire pieces into substantially U-shaped elbows be, the middle leg of the U-shaped angle pieces squeezed and trimmed to the rectangular flat piece and at least one separate winding element in shape a rectangular flat part end with at least one other leg of the U-shaped elbow to form the armature winding is connected. A circumferential winding of In this way generated armature winding then consists one of the U-shaped elbow and the separate Rectangle flat part formed unit, which end with connected to one or more such units is.

Als Ausgangsmaterial können Drahtmaterialien mit im wesentlichen rechteckförmigem oder auch rundem Querschnitt eingesetzt werden. Falls im letztgenannten Fall bei den zwischen den als Flachteile ausgebildeten Wicklungselementen angeordneten, diese verbindenden Wicklungselementen ein rechteckförmiger Querschnitt erwünscht ist, so wird der Querschnitt zumindest der nicht zur Ausbildung eines Rechteck-Flachteils vorgesehenen Abschnitte des Drahtmaterials zu einem im wesentlichen rechteckigen Querschnitt umgeformt. Hierbei kann entweder das eingesetzte Drahtmaterial oder können die abgelängten Drahtstücke einer Querschnittsumformung unterzogen werden. Ferner ist es insbesondere bei der Verfahrensvariante zur Herstellung L - förmiger Winkelstücke denkbar, daß der Querschnitt des nicht zur Ausbildung eines Rechteck-Flachteils vorgesehene Schenkel der Winkelstücke nach Biegen derselben umgeformt wird.As a starting material can wire materials with substantially rectangular or round cross section used become. If in the latter case at the between arranged the winding elements designed as flat parts, these connecting winding elements a rectangular Cross section is desired, so is the cross section at least not for the formation of a rectangular flat part provided sections of the wire material to formed a substantially rectangular cross-section. Either the used wire material or The cut lengths of wire can be a cross-sectional deformation be subjected. Furthermore, it is particularly in the Process variant for producing L-shaped angle pieces conceivable that the cross section of not forming a Rectangular flat part provided legs of the angle pieces after bending the same is transformed.

Die Winkelstücke werden vorzugsweise durch Warmumformung gebogen.The angle pieces are preferably by hot forming bent.

Um die Geometrie, insbesondere die Dicke, der Rechteck - Flachteile während der Herstellung zu kontrollieren und auf diese Weise jeglichen Ausschuß zu vermeiden, werden die Flachteile bevorzugt durch mehrstufiges Pressen gequetscht. Ferner ist auf diese Weise eine einfache und reproduzierbare Variation der Geometrie der Flachteile möglich.Around the geometry, in particular the thickness, the rectangle - Control flat parts during manufacture and on to avoid this way any committee will be the Flat parts preferably squeezed by multi-stage pressing. Furthermore, in this way a simple and reproducible Variation of the geometry of the flat parts possible.

In Weiterbildung ist vorgesehen, daß jeweils der endständige Schenkel der Winkelstücke an seinem dem Rechteck-Flachteil abgewandten Ende in einer zu der Ebene des Rechteck-Flachteils parallelen Ebene abgeflacht wird. Das abgeflachte Ende dieses Schenkels dient dann zum Festlegen des Winkelstücks an dem endständigen Rechteck-Flachteil eines weiteren Winkelstücks. Ferner kann das endständige Rechteck-Flachteil der Winkelstücke an seinem dem anderen Schenkel abgewandten Ende mit einer Ausnehmung zum Festlegen des endständigen Schenkels eines weiteren Winkelstücks versehen werden, wobei die Geometrie der Ausnehmung des Rechteck-Flachteils zweckmäßig dem abgeflachten Ende des anderen Schenkels des Winkelstücks angepaßt wird.In development it is provided that in each case the terminal Legs of the elbows at his the rectangle flat part opposite end in one to the plane of the rectangular flat part flattened parallel plane. The flattened End of this leg is then used to set the Elbow on the terminal rectangular flat part of a another angle piece. Furthermore, the terminal rectangular flat part the elbows at his other thigh opposite end with a recess for fixing the end leg of another elbow provided be, with the geometry of the recess of the rectangular flat part expediently the flattened end of the other Leg of the elbow is adjusted.

Wie bereits angedeutet, werden die Winkelstücke vorzugsweise endseitig miteinander bzw. die Winkelstücke endseitig mit den separaten Rechteck-Flachteilen verschweißt, insbesondere punktverschweißt.As already indicated, the angle pieces are preferably end to each other or the elbows end welded to the separate rectangular flat parts, in particular spot-welded.

Bei einer mittels eines Verfahrens der vorgenannten Art hergestellte Ankerwicklung eines Elektromotors mit im wesentlichen rechtwinklig miteinander verbundenen Wicklungselementen aus Metall sind jeweils gegenüberliegende Wicklungselemente aus einem Drahtmaterial endseitig durch jeweils gegenüberliegende Wicklungselemente in Form von Rechteck-Flachteilen miteinander verbunden und sind wenigstens zwei, ein Winkelstück bildende Wicklungselemente einstückig ausgebildet und endseitig mit wenigstens einem weiteren solchen Winkelstück oder mit einem separaten Wicklungselement, insbesondere einem Rechteck-Flachteil, verbunden. Die Wicklungselemente in Form von Rechteck-Flachteilen sind dabei von gequetschten Drahtstücken gebildet, indem jeweils wenigstens ein Schenkel der Winkelstücke gequetscht ist.

Fig. 1 zeigt eine schematische Ansicht einer Ankerwicklung 1 eines Elektromotors (nicht dargestellt). Die Ankerwicklung 1 ist von wendelförmigem Aufbau und weist etwa rechtwinklig miteinander verbundene Wicklungselemente 2, 3 aus Metall auf, von denen die jeweils gegenüberliegenden Wicklungselemente 2 von Drahtstücken 4 gebildet sind, die bei dem gezeigten Ausführungsbeispiel einen im wesentlichen rechteckigen Querschnitt aufweisen. Die jeweils gegenüberliegenden Wicklungselemente 3 sind von Rechteck-Flachteilen 5 gebildet, wobei die Drahtstücke 4 und die Rechteck-Flachteile 5 in Umfangsrichtung der Ankerwicklung 1 alternierend angeordnet und die Drahtstücke 4 mit den Rechteck-Flachteilen 5 jeweils endseitig im wesentlichen rechtwinklig verbunden sind. Fig. 1 shows a schematic view of an armature winding 1 of an electric motor (not shown). The armature winding 1 is of helical construction and approximately at right angles interconnected winding elements 2, 3 from Metal on, of which the respective opposite winding elements 2 of pieces of wire 4 are formed at the embodiment shown a substantially have rectangular cross-section. The opposite ones Winding elements 3 are of rectangular flat parts 5 formed, wherein the wire pieces 4 and the rectangular flat parts 5 in the circumferential direction of the armature winding 1 alternately arranged and the wire pieces 4 with the rectangular flat parts 5 each end substantially perpendicular connected are.

In der Fig. 2 ist ein Verfahrensschema zur Herstellung der Ankerwicklung 1 gemäß Fig. 1 dargestellt. Ein Drahtmaterial mit rundem Querschnitt wird zu Drahtstücken 10 abgelängt (Fig. 2a) und der Querschnitt der Drahtstücke 10 oder auch des Ausgangsmaterial zu einem im wesentlichen rechteckigen Querschnitt umgeformt (Fig. 2b). Sodann werden die Drahtstücke 10 insbesondere durch Warmumformung unter Bildung eines z.B. zwei Schenkel 11, 12 aufweisenden L- förmigen Winkelstücks 13 gebogen (Fig. 2c). Anschließend wird der Schenkel 11 des Winkelstücks 13 durch mehrstufiges Pressen bis zu der gewünschten Dicke gequetscht, wobei zunächst der dem Schenkel 12 zugewandte Abschnitt des Schenkels 11 gequetscht und letzterer erst anschließend über seine gesamte Länge gequetscht wird, um für einen Ausgleich des Materialverlustes am Biegeradius zu sorgen. Beim Pressen des Schenkels 11 wird das Drahtmaterial bis über seine Fließgrenze hinaus beansprucht (Fig. 2d). Schließlich wird der gequetschte Schenkel 11 des Winkelstücks 13 entlang einer in Fig. 2d strichpunktiert dargestellten Linie 14 unter Bildung eines endseitig mit dem anderen Schenkel 12 verbundenen Rechteck-Flachteils 15 beschnitten (Fig. 2e). Das Zuschneiden des Rechteck-Flachteils 15 kann beispielsweise mittels eines in die zum Quetschen des Schenkels 11 des Winkelstücks 13 vorgesehene Presse integrierten Schneidewerkzeuges durchgeführt werden.In Fig. 2 is a process scheme for the preparation of Armature winding 1 shown in FIG. 1. A wire material with a round cross section is cut to pieces of wire 10 (Fig. 2a) and the cross section of the wire pieces 10 or also of the starting material to a substantially rectangular Cross-section formed (Fig. 2b). Then the wire pieces 10 in particular by hot forming under formation of e.g. two legs 11, 12 having L-shaped Elbow 13 bent (Fig. 2c). Subsequently, the Leg 11 of the angle 13 by multi-stage pressing squeezed to the desired thickness, initially the the leg 12 facing portion of the leg 11 squeezed and the latter only afterwards over its entire Length is crushed to compensate for material loss to provide the bending radius. When pressing the thigh 11, the wire material is above its yield point also claimed (Figure 2d). Finally, the bruised Leg 11 of the angle 13 along a in Fig. 2d shown in phantom line 14 under formation one end connected to the other leg 12 Rectangular flat part 15 cropped (Fig. 2e). The cropping the rectangular flat part 15 can, for example by means of a in the squeezing of the leg 11 of the Elbow 13 provided press integrated cutting tool be performed.

Ferner wird der Schenkel 12 des Winkelstücks 13 an seinem dem Rechteck-Flachteil 15 abgewandten Ende 16 in einer zu der Ebene des Rechteck-Flachteils 15 parallelen Ebene abgeflacht, um ihn an dem dem Schenkel 12 abgewandten Ende 17 des Rechteck-Flachteils 15 eines weiteren Winkelstücks 13 festzulegen, z.B. zu verschweißen, verlöten oder dergleichen. Das Ende 17 des Rechteck-Flachteils 15 wird zum selben Zweck mit einer Ausnehmung 18 versehen, die das abgeflachte Ende 16 eines weiteren Winkelstücks 13 aufnimmt.Furthermore, the leg 12 of the angle 13 at its the rectangular flat part 15 facing away from end 16 in one flattened the plane of the rectangular flat part 15 parallel plane, to him at the end facing away from the leg 12 17th the rectangular flat part 15 of another angle 13th determine, e.g. to weld, solder or the like. The end 17 of the rectangular flat part 15 becomes the same Purpose provided with a recess 18, which flattened End 16 of another elbow 13 receives.

Zur Herstellung der Ankerwicklung 1 gemäß Fig. 1 wird jeweils das Ende 18 des Rechteck-Flachteils 15 der Winkelstücke 13 mit dem abgeflachten Ende 16 des Schenkels 12 weiterer Winkelstücke 13 im wesentlichen rechtwinklig verschweißt, insbesondere punktverschweißt, so daß sich der wendelförmige Aufbau der Ankerwicklung 1 ergibt (Fig. 1). Aufgrund der Ausbildung jeweils zweier benachbarter Wieklungselemente 2, 3 aus einem einzigen Drahtstück 10 (Fig. 2) sind zur Herstellung der Ankerwicklung 1 weniger Schweißvorgänge als bei den herkömmlichen Verfahren erforderlich und wird insbesondere die anfallende Menge an Ausschußmaterial im Vergleich zu gestanzten Rechteck-Flachteilen um etwa 70% verringert.To produce the armature winding 1 according to FIG. 1, respectively the end 18 of the rectangular flat part 15 of the angle pieces 13 with the flattened end 16 of the leg 12th further angle pieces 13 welded substantially at right angles, in particular spot welded, so that the helical structure of the armature winding 1 results (Fig. 1). Due to the formation of two adjacent Wieklungselemente 2, 3 of a single piece of wire 10 (Fig. 2) are less for producing the armature winding 1 Welding operations required as in the conventional methods and in particular, the accumulated amount of scrap material in comparison to punched rectangular flat parts reduced by about 70%.

Fig. 3 ist eine zu dem L-förmigen Winkelstück 13 gemäß Fig. 2e alternative Ausführungsform eines rechteckförmigen Winkelstücks 13a entnehmbar. Das Winkelstück 13a unterscheidet sich von dem Winkelstück 13 der Fig. 2e im wesentlichen dadurch, daß es zwei gegenüberliegende Schenkel 12 aus einem Drahtstück aufweist, die an ihrem in Fig. 3 linken Ende durch ein Rechteck-Flachteil 15 miteinander verbunden sind. An dem in Fig. 3 rechten Ende des oberen Schenkels 12 ist ein weiteres - endständiges - Rechteck-Flachteil 15 angeordnet, dessen freies Ende 17 in Zeichnungsebene oberhalb dem freien Ende 16 des in Fig. 3 unteren endständigen Schenkels 12 des Winkelstücks 13a angeordnet ist. Die Herstellung des Winkelstücks 13a entspricht im wesentlichen dem Verfahrensschema nach Fig. 2, wobei die abgelängten Drahtstücke 10 (Fig. 2b) jedoch zu den rechteckförmigen Winkelstücken 13a gebogen, jeweils zwei gegenüberliegende Schenkel 11, 12 der rechteckförmigen Winkelstücke 13a gequetscht und zu den Rechteck - Flachteilen 15 beschnitten werden. Im Falle einer aus mehreren solcher Winkelstücke 13a aufgebauten Ankerwicklung kann die Anzahl an Schweißvorgängen im Vergleich zu einer aus L-förmigen Winkelstücken 13 (Fig. 2e) aufgebauten Ankerwicklung um die Hälfte reduziert werden.FIG. 3 is a view to the L-shaped angle 13 of FIG. 2e alternative embodiment of a rectangular angle piece 13a removable. The elbow 13a is different essentially from the angle 13 of FIG. 2e, that there are two opposite legs 12 of a Wire piece, which at its left in Fig. 3 end are connected by a rectangular flat part 15 with each other. At the right in Fig. 3 end of the upper leg 12 is another - terminal - rectangular flat part 15 arranged its free end 17 in the plane above the free end 16 of the bottom in Fig. 3 terminal Leg 12 of the elbow 13a is arranged. The production of the elbow 13a substantially corresponds the process scheme of Fig. 2, wherein the cut to length Wire pieces 10 (Fig. 2b) but to the rectangular Elbows 13a bent, two opposite each Leg 11, 12 of the rectangular angle pieces 13 a squeezed and cut to the rectangular flat parts 15 become. In the case of one of several such elbows 13a constructed armature winding can the number of welding operations compared to one of L-shaped elbows 13 (Fig. 2e) constructed armature winding by half be reduced.

In der Fig. 4 ist eine weitere zu dem L-förmigen Winkelstück 13 gemäß Fig. 2c alternative Ausführungsform eines U-förmigen Winkelstücks 13b gezeigt, welches entsprechend dem in der Fig. 3 dargestellten Winkelstück 13a zwei gegenüberliegende Schenkel 12 aus einem Drahtstück aufweist. Die Schenkel 12 sind an ihren in Fig. 4 linken Ende durch ein Rechteck-Flachteil 15 miteinander verbunden, während das in Fig. 4 rechte freie Ende 16 jedes Schenkels 12 abgeflacht ist, um es mit einem (nicht gezeigten) separaten Rechteck-Flachteil mit dem Rechteck-Flachteil 15 des Winkelstücks 13b etwa entsprechenden Abmessungen zu verbinden. Im Falle einer aus mehreren solcher über separate Rechteck-Flachteile verbundener Winkelstücke 13b aufgebauten Ankerwicklung entspricht die Anzahl an Schweißvorgängen derjenigen der Ausführungsform gemäß Fig. 2.In Fig. 4 is another to the L-shaped elbow 13 as shown in FIG. 2c alternative embodiment of a U-shaped Elbow 13b shown which according to in Fig. 3 illustrated angle piece 13a two opposite Leg 12 has a piece of wire. The Legs 12 are at their left in Fig. 4 end by a Rectangle flat part 15 connected to each other while the in Fig. 4 right free end 16 of each leg 12 flattened is to make it with a separate rectangular flat piece (not shown) with the rectangular flat part 15 of the elbow 13b about corresponding dimensions to connect. In the event of one of several such over separate rectangular flat parts connected angle pieces 13b constructed armature winding corresponds to the number of welding operations of those the embodiment of FIG. 2.
